The publication of the CBSE (Central Board of Secondary Education) Class 12 Marking Scheme has been done recently. There are generally two terms in Class 12 named terms 1 and 2. The nature of the term 2 examinations would usually be situationbased, casebased, subjective, openended shorttype questions. However, most questions which are asked in both the terms are objectivebased.
In this informative article, we have organised a list of topics for Physics – Chemistry – Maths and Physics – Chemistry – Biology students. These topics would include various sets of information regarding the distribution and weightage of marks, important books for reference, how to score maximum marks in each subject, etc. So, before diving deep into them, let us talk about a few things related to the syllabuses of all the subjects, along with their significance.
Important Highlights of the Exam
Before appearing for the CBSE Class 12 Term 2 examination, the students should understand the major importance and other highlights. The following are a few points:
 Understanding the marking scheme would ease off the students’ minds and clarify what to study.
 It will also help them prioritise the topics based on the level of importance or the level of difficulty, whichever with which the students feel more comfortable.
 It will enhance the scope of securing maximum marks in the examination.

Importance of Knowing the Syllabus
Having an overall idea of the Class 12 syllabus will have major advantages for the students who appear for the exams. Given below are the few set of the major importance of knowing the syllabus:
 It is a must for every student to know what the syllabus is because it will help them have an overall idea of the subject they are studying.
 They will be able to identify the most important and least important topics.
 Furthermore, if a chapter contains problems, understanding the syllabus will help students know what the problem is about and what it says.
 It will help them encounter learning formulas.
 It will improve their confidence level and help boost their morale.
